Reply to comment by jrhoffa in TIL the Passemant astronomical clock in Versailles has shown the correct date, time, moon phase, planetary alignment, etc (accounting for leap years ) from 1750 and can display through 9999. by kitkatbloo
France adopted the Gregorian (modern ) calendar in 1782. Since then,1800 and 1900 have not been leap years, but I presume this clock was built to the old rules where they would be leap years.
